JOSEPH D. SMITH, or RISING CITY, NEBRASKA.

FILTER.

SPECIFICATION forming part of Letters Patent N 0. 333,896, dated January 5, 1886.

Application filed September 26, 1885. Serial No. 178,272. (No model.)

To a whom it may concern.-

Be it known that I, Josnrn D. SMITH, a citizen of the United States of America, residing at Rising City, in the county of Butler and State of Nebraska, have invented certain new and useful Improvements in Filters; and I do hereby declare the following to be a full,

clear, and exact description of the invention, I

such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to certain new and useful improvements in filterers for cisterns or wells; and it consists in the construction and combination of parts, as will be hereinafter fully set forth, and specifically pointed out in the claim.

In the accompanying drawings,which illustrate my invention, Figure 1 is a sectional view of my improved filterer, showing the same in position in a well or cistern. Fig. 2 is a sectional view taken through the line or x of Fig. l.

In the drawings I have shown my invention applied to the center portion of a well or cistern below the water-level,so that the same may be entirely submerged.

A represents a receptacle, the sides and bottom of which are made of a solid material--as sheet metal--and said receptacle is open at its top, which top or opening is provided with a perforated covering-plate, B, with adepending rim, 1), which fits over and securely holds the same upon the upper edge of the receptacle A. The top or covering plate, B, is provided with a central opening, through which passes the suction-pipe G, to the upper end of which is attached a pump.

To the center portion of the'bottom of the receptacle A is attached a cylinder, D, of wiregauze or other perforated material, which is provided with a top, d, through which the lower end of the tube 0 is secured. After the compartment D is secured in place, and the pipe made fast thereto, the receptacle A is filled with a filtering medium, which preferably consists of charcoal and gravel.

E represents a covering-plate, which is pro vided with a central opening at its apex, through which the suction-tube 0 passes, and at its periphery with a depending flange e, which extends below the top of the receptacle A, and said flange is provided with inwardly projecting supports f, which rest upon the top B of the receptacle A, so as to hold the covering-plate in position. The diameter of the coveringplate E is greater than the diameter of the receptacle A, which contains-the filtering medium, so that apassage-way will beprovided between the same.

By providing the conical cover with a depending flange, as shown, the impurities in the water as they settle are prevented from coming in contact with the upper perforated portion of the receptacle, and by having a receptacle for the filtering medium with closed sides and bottoms the impurities which settle upon the bottom of the cistern will not be disturbed as the water is drawn into the reservoir D.

A filter constructed as hereinbefore described can be readily removed from the cistern or well by hoisting the same out with a suction-rod, G.

I claim- The improved filterer for cisterns,herein described, consisting of a receptacle, A, having a perforated top and closed bottom, a compartment, D, located within said receptacle and having perforated sides, a tube, 0, depending into the receptacle A,to communicate with the compartment-filtering medium located in said receptacle, and a covering-plate supported by said tube and provided with a flange depending below the top of the receptacle, and braced relative thereto by supports ff, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
